The data rate of ZigBee is 250kbps at 2.4GHz, 40kbps at 915MHz and 20kbps at 868MHz whereas that of Bluetooth is 1Mbps. –Configuration: ZigBee uses a basic master-slave configuration suited to static star networks of many infrequently used devices that talk via small data packets. ›It allows up to 254 nodes. ›Bluetooth’s protocol is more complex since it is geared towards handling voice, images and file transfers in ad hoc networks. ›Bluetooth devices can support scatternets of multiple smaller non-synchronized networks(piconets). 8 Slaves or nodes in a baisc master slave piconet set up. – Wake up Time: When ZigBee node is powered down, it can wake up and get a packet in around 15 msec whereas a Bluetooth device would take around 3sec to wake up and respond.
